Utilization of manipulative teaching aids to grow the numerical ability of students with disabilities

Children with disabilities (CwD) have limitations in conceptual understanding of mathematics. Lack of numerical conceptual understanding will cause CwD to experience difficulty in counting. The purpose of this case study was to analyze the growth of numerical abilities of students with disabilities through the application of manipulative teaching aids. This research method used a qualitative approach. The subjects of this study were students of the seventh grade of the State Extraordinary School of Salatiga (SLBN) who had limited vision, mind, hearing, or speech impairment. After the results of the students' work were corrected, the qualitative data analysis was done by analyzing the results of the test, interview, and triangulation data. The results of this research: Through the use of Manipulative Teaching Aids, the numerical abilities of CwD could be improved and developed. It is recommended that teachers in ES should use Manipulative Teaching Aids so that the numerical abilities of CwD can be improved and developed.
